One of a number of lines or parts diverging from a common point or center, like the radii of a circle; as, a star of six rays.
One of a system of diverging lines passing through a point, and regarded as extending indefinitely in both directions. See Half-ray.
a hypothetical line used to represent a single stream of light. Rays show the path of light but do not exist in nature.
Part of a line, containing one endpoint and extending to infinity in one direction.
A beam of electromagnetic energy following an elemental path perpendicular to the radiation's wave front.
(3) A straight path that extends infinitely from a point, called its endpoint. A ray is named by its endpoint and another point on the ray.
A part of a line that has one endpoint and extends in one direction without end.
A part of a line with a single endpoint and that extends infinitely in one direction
A straight line with one endpoint. The line extends infinitely.
A straight line, representing light, perpendicular to the light wave front and traveling in the same direction. At a boundary surface, or interface such as the surface between a fiber core and cladding, the ray may change direction suddenly, but it remains a straight line.
a line having one endpoint
A straight line drawn from the origin of a diagram. In the Heckscher-Ohlin Model, two rays are used to define a diversification cone.
a straight line representation of the path of a light wave.
a one-dimensional figure that consists of one endpoint a, one point B, all of the points on , and all points for which B is between them and A; written [Go to source
A straight line that begins at a point and continues outward in one direction.
The ray AC consists of segment AC and all other points P such that C is between A and P. The point named first, here A, is the endpoint of Ray AC.
A line that starts from some point and goes off into space. If capital is on one axis and labor is on the other, a ray from the origin describes all input combinations where the capital-labor ratio is constant.
A straight line extending from point to point.
A portion of a line with one endpoint that goes off to infinity.
a half-line. Continues forever in one direction. Has one endpoint.
Has exactly one endpoint and extends indefinitely in one direction along a straight path.
A part of a line that has one endpoint and continues without end in one direction.
A line that has one end-point, but continues infinitely in the other direction.
straight line path of light, perpendicular to the wave fronts
part of a line with one end point
a straight line extending from a point
is a one side infinite geodesic which is minimizing on each interval
A straight line representing the direction of a ray or bundle of rays of light. An element of geometrical optics.
A set of points that has one endpoint and that extends without end in one direction
a portion of a line that begins at a point and goes on forever in one direction.
A straight path that extends infinitely in one direction from a point, called its endpoint.
Beginning at a point on a line and continuing in one direction through all points on that line.
A ray (also called a half line) is a straight line that extends infinitely far in one direction from a point.
one if the bony spines supporting the membrane of a fish's fin. it extends in the form of a straight line from the body. you can count the number of rays in a betta's dorsal for example.
a straight line that represents the motion of light in one direction
Ray AB is the part of that contains point A and all the points on that are on the same side of as . Point A is the endpoint of (Lesson 2.1).
A part of a line that has one endpoint and goes on forever (infinitely) in one direction.
A geometric representation of a light path through an optical medium; a line normal to the wavefront indicating the direction or radiant energy flow.
A part of a line that has one end point and continues infinitely in one direction.
XY consists of 3FY and all points P such that Y is between X and P.
